The Prompt

An Ageing Population

In many countries, people are now living longer than ever before. Some people say an ageing population creates problems for governments. Other people think there are benefits if society has more elderly people.

To what extent do the advantages of having an ageing population outweigh the disadvantages?

Give reasons for your answer and include any relevant examples from your own knowledge or experience.

Band 9

277 words

Explains the specific fiscal mechanism behind the disadvantages rather than only asserting that ageing populations "cost more".

As life expectancy continues to rise across much of the world, many governments face the challenge of an increasingly elderly population, and while this demographic shift brings genuine benefits, I believe its disadvantages currently outweigh them in most countries lacking adequate policy responses.

There are genuine advantages to an ageing population. Older citizens often possess decades of accumulated knowledge and experience that benefit workplaces, communities, and younger generations alike, whether through mentorship, volunteering, or continued part-time work. Many elderly people also provide invaluable, often unpaid, childcare support to their extended families, allowing younger relatives to remain in the workforce.

However, I believe the disadvantages are currently more significant, particularly the substantial economic burden an ageing population places on governments. As the proportion of retired citizens grows relative to working-age taxpayers, pension systems and public healthcare services face mounting financial strain, since elderly populations typically require significantly more medical care than younger ones. Simultaneously, a shrinking working-age population can reduce a country's overall economic productivity and tax revenue precisely when demand for age-related public spending is rising fastest, creating a genuinely difficult fiscal squeeze.

That said, I believe these disadvantages are not inevitable but rather reflect inadequate preparation. Countries that raise retirement ages gradually, encourage continued part-time employment among older citizens, and invest early in efficient elderly healthcare systems can substantially reduce this economic burden while preserving the genuine social benefits an experienced older population provides.

In conclusion, while an ageing population offers real benefits through accumulated experience and family support, I believe the economic disadvantages currently outweigh them in most countries, primarily because governments have been slow to adapt pension and healthcare systems to this demographic shift.

Examiner Notes

Task Response: Fully addresses the extent question with a clear position, genuine acknowledgement of real advantages, and a detailed explanation of the fiscal mechanism behind the disadvantages.

Coherence & Cohesion: Ideas progress logically from advantages to disadvantages to a solution-oriented counterpoint, with cohesive devices ("however", "that said") managing each shift smoothly.

Lexical Resource: Wide range of precise vocabulary ("fiscal squeeze", "mentorship", "demographic shift") used with natural collocation throughout.

Grammatical Range & Accuracy: Wide range of complex structures, including concession clauses, used with full accuracy.

Band 8

256 words

Clearly argued with relevant reasoning, just slightly more general in its supporting detail than a band 9 answer.

As people live longer in many countries, governments face the challenge of an ageing population, and while this brings real benefits, I believe the disadvantages currently outweigh them in most countries.

There are genuine advantages to having more elderly people in society. Older people often have years of knowledge and experience that can benefit workplaces and communities, whether through mentoring or continuing to work part-time. Many elderly people also help look after grandchildren, which allows younger family members to keep working.

However, I believe the disadvantages are currently bigger, especially the economic burden on governments. As more people retire compared to those still working, pension systems and healthcare services come under a lot of financial pressure, since older people usually need more medical care. At the same time, having fewer working-age people can reduce a country's economic productivity just when spending on older people is increasing.

That said, I do not think these problems are unavoidable. Countries that gradually raise the retirement age and encourage older people to keep working part-time can reduce this economic burden while still benefiting from their experience.

In conclusion, while an ageing population brings real benefits through experience and family support, I believe the economic disadvantages currently outweigh them in most countries, mainly because governments have been slow to adapt their systems. Countries such as Japan, which has one of the world's oldest populations, illustrate this challenge clearly, since its government continues to struggle with rising healthcare costs and a shrinking workforce despite decades of advance warning about this demographic trend.

Examiner Notes

Task Response: Fully addresses the extent question with a clear position and relevant reasoning, though slightly more general than the band 9 answer's.

Coherence & Cohesion: Clear five-paragraph structure with accurate cohesive devices throughout.

Lexical Resource: Good range of vocabulary, though "a lot of financial pressure" is more general than the higher-band answer's more precise phrasing.

Grammatical Range & Accuracy: Mostly accurate complex sentences with only rare minor slips.

Band 7

253 words

A clear, well-reasoned position that would be stronger with the pension and healthcare strain developed further.

In many countries, people are living longer, and I think the disadvantages of an ageing population currently outweigh the advantages.

There are some benefits to having more older people. They often have a lot of experience that can help younger people, and many grandparents help look after their grandchildren so parents can keep working.

However, I think there are bigger problems. Governments have to spend more money on pensions and healthcare for older people, and there are fewer young workers to pay taxes for this spending. This creates financial pressure on the government.

I do not think this problem cannot be solved, though. If governments raise the retirement age slowly and let older people keep working part-time, this could help reduce the problem.

In conclusion, I think an ageing population brings some benefits, but overall the economic disadvantages are currently bigger, mainly because governments have not adapted their systems enough. Japan is a good example of a country facing this exact challenge, since it has one of the oldest populations in the world, and its government has struggled for many years with rising healthcare costs and a shrinking number of workers to support the growing number of retired people. Other countries could learn from Japan's experience by preparing much earlier, for example by encouraging people to save more for their own retirement and by making it easier for older workers to remain in employment for longer if they choose to, rather than waiting until the financial pressure becomes very severe before taking action.

Examiner Notes

Task Response: Addresses the extent question with a clear position and relevant reasoning, but the fiscal mechanism is not developed in as much depth as in the higher-band answers.

Coherence & Cohesion: Organised logically with advantages, disadvantages, and a possible solution in separate paragraphs; cohesive devices ("However", "In conclusion") are accurate but predictable.

Lexical Resource: Adequate range for the task, with some repetition of "problem" and "government" throughout.

Grammatical Range & Accuracy: Generally accurate mix of simple and complex sentences; meaning is always clear.

Band 6.5

253 words

The position and reasoning are both clear, but agreement errors appear in almost every sentence.

In many country, people is living longer, and I think the disadvantage of an ageing population currently outweigh the advantage.

There is some benefit to having more older people. They often have a lot of experience that can help younger people, and many grandparent help look after their grandchild so parent can keep working.

However, I think there is bigger problem. Government have to spend more money on pension and healthcare for older people, and there is fewer young worker to pay tax for this spending. This create financial pressure on the government.

I do not think this problem cannot be solve, though. If government raise the retirement age slowly and let older people keep working part-time, this could help reduce the problem.

In conclusion, I think an ageing population bring some benefit, but overall the economic disadvantage is currently bigger, mainly because government have not adapted their system enough.

Examiner Notes

Task Response: Addresses the extent question with a clear position, matching the content of the band 7 answer, but grammar errors throughout reduce clarity.

Coherence & Cohesion: Follows the same five-part structure as the higher-band answers.

Lexical Resource: Limited by missing plurals on key task words ("country", "government", "worker") used throughout instead of their plural forms.

Grammatical Range & Accuracy: Frequent subject-verb agreement errors ("people is living", "there is bigger problem", "government have to spend") appear on nearly every sentence.

Band 4-5 - What to Avoid

29 words

States one advantage and one disadvantage but never weighs them against each other, and stays well under the required length.

I think old people is good for family.

But government spend more money for them, this is problem.

It is difficult question, this is my opinion about this topic.

Examiner Notes

Task Response: Gives only a single unsupported sentence for the advantages and one for the disadvantages, so the extent question is never genuinely addressed. At well under 250 words, the response is also underlength.

Coherence & Cohesion: Paragraphs are short, disconnected statements with minimal linking.

Lexical Resource: Vocabulary is basic and repetitive ("good", "problem", "think") with little variation.

Grammatical Range & Accuracy: Frequent errors throughout ("old people is good", "government spend more money").
